Nobody knows what's in a black hole, but you know that your climbing, hiking, and traveling gear is in Patagonia's Black Hole 45L Duffel Bag. Inspired by rugged yet light alpine packs, the Black Hole features a burly ripstop fabric filmed in a TPU laminate and coated with DWR for the ultimate in wilderness worthy protection. The padded base protects your gear throughout the trip. Internal organizers and zippered mesh pockets organize all the small things, while the external side pocket stows the duffel for compact storage. Compression straps prevent your gear from bouncing around whether you're traveling via airplane or four wheeler.
